摘要
文〔1〕提出了求解弹塑性裂纹尖端场的一种比拟方法.本文把文〔1〕提出的比拟方法推广到一般弹塑性力学问题上,导出了几个典型问题的解,并作了相应的有限元数值分析.分析结果表明,该方法给出了真正弹塑性意义下的解答.
An analogy scheme,proposed by Tian in 1999 for the determination of the elastic-plastic crack-tip fields,is used for solving gneral elastic-plastic problems.Solutions of two typical problems are worked out and checked by the finite element method.The mechanic fields are proved to be the real solutions in the general elastic-plastic sense.
